SAFETY-RAZOR.

Specification of Letters Patent.

Patented Jan. 2, 1912.

Application filed August 20, 1910. Serial No. 578,163.

Tb all whom it may concern:

Be it known that I, VILLIABL V. BA ER, a

citizen of the United States, residing at Richmond Hill, in the countyof Queens and State of New York, have invented certain new and usefulImprovements in Safety- R-azors, of which the following is aspecification.

My present invention relates to improvements in safety razors, theadvantages of which will appear from an understanding of the followingdescription in connection with the annexed drawings, showing one of theforms my improvements may take.

In the drawings, Figure 1' is an elevation of a safety razor within myinvention; Fig. 2 is a plan view of the razor of Fig. 1 showing the topplate of the blade holder in open position Fig. 3 is a partial view ofthe razor on an enlarged scale, same being a vertical section partly inelevation taken on the line 33 in Fig. 4 looking in the direction of thearrow and indicating in dotted lines how the blade holder may be swunginto longitudinal position relative to the handle to permit the razor tobe used with a stroke similar to an ordinary razor; Fig. partly inelevation on the line 44 in Fig. 3; and Fig. 5 is a view of the bladedetached from the holder.

I will now describe the devices of the drawings reserving it to theclaims to point out the novel features and to indicate the scope of theinvention, it being understood that the claims will be given due rangeof equivalents. v

Briefly speaking, the razor consists of a blade,a blade holder, ahandle, and connecting devices between the blade holder and handle.

The blade consists of two parts, a-thin sheet-steel sharpened member 1and a stiifening member 2, these being integrally united. Thesheet-steel portion is shown sharpened along two edges 1 although ofcourse it might be sharpened at only one edge. The stiffening portion 2is applied to the sheet-steel portion by wrapping a suitably thick metalstrip lengthwise around the blade between its cutting edges, the ends 2of the strip being dove-tailed together. The

thickness and the width of the stifiening strip are such that anyflexibility of the sheetsteel member is el1minated, so much so that theblade can bezused for shaving 1' is a vertical section withoutadditional support like an ordinary razor.

The blade holder consists of a bottom plate 3 and a top plate 4 hingedtogether at 5 and adapted to releasably interlock with each other at 6.The bottom plate 3 has a recess in its upper face (compare Figs. 3 and4) adapted to receive snugly between its sides 3- the portion of thestifl'ening strip 2 that is below the sheet-steel part 1 of the bladewhen laid on the bottom plate of the holder as shown in Figs. 2 to 4inclusive. Guard teeth 7 are provided on the bottom plate of the holderunder the cutting edges of the blade. The top plate of the holder whenhlnged down into closed position as shown 1n Figs. 3 and 4 cont-actswith the top of the blade and due to the resilient lock 6 holds theblade rigidly in the recess in the bottom plate of the holder. The bladeholder is attached to the handle 8 by a piv: otal connect-ion permittingthe former to be pivoted and locked in any angular position relatlve tothe handle or in parallelism therewith. For this purpose the upper endof the handle is screw-threaded to engage internal threads of a sleeve9, the upper or mouth portion of which projects beyond the top of thehandle and also inwardly so as to form a socket adapted to receive andconfine a ball 10 connected by a neck 10 with a projection 10 from thebottom plate of the holder. The mouth of the sleeve is provided with twoor four equally spaced vertical notches 9 to receive the neck 10 of theprojection when the blade holder is swung into angular positions or intoparallelism with the handle. (See Fig. 3.) Whatever the position ofadjustment of the blade holder; it

may be locked in that position by screwing up the sleeve on the handleso that the ball is confined or locked between the upper portion of thesleeve and the end of the handle.

Some of the advantages of the construe-- tion are: The stifi'ening stripis integrally secured to the sheet metaF part of the blade withoutdrilling holes through the blade or even notching it. This saves notonly these. operations but also saves preliminarily drawing the temperof the steel and thereafter retempering. Similarly, the blade is heldfixedly in the blade holder without resorting to any complication ofopenings or notches in the blade to co-act with a correspondingcomplication of projections on the holder. Further, the holder can beinstantly adjusted and locked in any desired 'shaving position relativeto the handle. In this way it perfectly adapts itself to the needs ofright and left handed users. Furthermore, the holder when-adjusted intolongitudinal relation to the handle, makes possible the same-shavingstroke given by an ordinary razor and which is so much preferred by mostusers over the hoe-like stroke of razors in which the blade holder issecured at right angles to the handle.

Having thus described my invention, what I claim is 1. A safety razorblade consisting of a thin sharp-edged sheet-steel member, and astiifening strip wrapped lengthwise around sharp-edged member and a saidmember, said strip having interlocking means at its ends for securingsaid ends together, and being thereby rigidly secured to said member. a1

2. A safety razor blade, comprising a thin stiffening strip wrappedlengthwise around said member, one end of the strip having asubstantially dovetailed socket and the other end having substantially adovetail that engages in the socket to secure the ends together.

In testimony whereof I aflix my signature in presence of two witnesses.
